BICEP/Keck XXII: Analysis of the South Pole Atmosphere for CMB Observations
P. A. R. Ade, Z. Ahmed, M. Amiri +92
The South Pole is among the driest sites on Earth, and the resulting high atmospheric transparency makes it an excellent site for millimeter-wave astronomical observations. Neverth…
Status of BICEP Array and Integration of the 220/270 GHz Receiver
A. Steiger, P. A. R. Ade, Z. Ahmed +83
Measurements of the polarization of the cosmic microwave background are critical for modern cosmology as they constrain the physics of the early universe and cosmic inflation. BICE…
Optics and broadband anti-reflection coatings for the BA4-90/150 receiver
A. R. Polish, P. A. R. Ade, Z. Ahmed +84
The BICEP Array telescopes search for primordial B-mode polarization from inflationary gravitational waves. This signal is exceedingly faint, demanding excellent map depth and syst…
Advanced Time-Division Multiplexed Readout Chain for the BICEP Array 90/150 GHz Receiver
B. Cantrall, P. A. R. Ade, Z. Ahmed +89
This work presents the current performance of the advanced time-division multiplexed (TDM) readout chain for the BICEP Array 90/150 GHz receiver. BA4-90/150, scheduled for deployme…
Optical characterization of the BICEP array 150 and 220/270GHz CMB polarimeters in the 2026 season
M. Izquierdo Poza, P. A. R. Ade, Z. Ahmed +82
BICEP Array (BA) is the current-generation instrument in the BICEP series of small-aperture, on-axis refracting telescopes at the South Pole, designed to constrain the tensor-to-sc…
Overview and status of BICEP Array's BA4-90/150 CMB polarimeter
M. A. Petroff, P. A. R. Ade, Z. Ahmed +83
The inflation paradigm postulates a period of rapid expansion in the early Universe, which would generate gravitational waves. These tensor perturbations would produce a faint B-mo…
Improved Absolute Polarization Calibrator for BICEP CMB Polarimeters
A. R. Polish, P. A. R. Ade, Z. Ahmed +89
Cosmic birefringence is a hypothesized parity violation in electromagnetism that predicts a frequency-independent polarization rotation as light propagates. This would rotate the l…
The Simons Observatory: Science Goals and Forecasts for the Enhanced Large Aperture Telescope
The Simons Observatory Collaboration, M. Abitbol, I. Abril-Cabezas +419
We describe updated scientific goals for the wide-field, millimeter-wave survey that will be produced by the Simons Observatory (SO). Significant upgrades to the 6-meter SO Large A…
The LiteBIRD mission to explore cosmic inflation
T. Ghigna, A. Adler, K. Aizawa +156
LiteBIRD, the next-generation cosmic microwave background (CMB) experiment, aims for a launch in Japan's fiscal year 2032, marking a major advancement in the exploration of primord…
Testbed preparation of a small prototype polarization modulator for LiteBIRD low-frequency telescope
Thuong D. Hoang, Tomotake Matsumura, Ryota Takaku +9
LiteBIRD is the Cosmic Microwave Background (CMB) radiation polarization satellite mission led by ISAS/JAXA. The main scientific goal is to search for primordial gravitational wave…
Testing magnetic interference between TES detectors and the telescope environment for future CMB satellite missions
Tommaso Ghigna, Thuong Duc Hoang, Takashi Hasebe +11
The two most common components of several upcoming CMB experiments are large arrays of superconductive TES (Transition-Edge Sensor) detectors and polarization modulator units, e.g.…
QUBIC IV: Performance of TES Bolometers and Readout Electronics
M. Piat, G. Stankowiak, E. S. Battistelli +126
A prototype version of the Q & U bolometric interferometer for cosmology (QUBIC) underwent a campaign of testing in the laboratory at Astroparticle Physics and Cosmology laboratory…
